Bull of Heaven is noise, or drone, or really, whatever the hell it feels like. The duo just released another recording, Plucked for the Breast of the Dead. The tracks range in length from a couple minutes to the 50,000 hour long (that's over five years, in case you don't want to do the math) "Like a Wall in Which an Insect Lives and Gnaws."
The length is reached by using loops, leaving equipment on while recording it and other time saving tricks. In the history of music, there have been similar feats attempted. John Cage's "Organ²/ASLP," is currently being played in a church in Germany; the performance will be finished in 2640. Cage's composition might be big, but it doesn't hold a torch to Ian D. Mellish's "Olitsky," a loop intended to last 1,600,000 years.
As far as Bull of Heaven is concerned, it's only going to get bigger, longer and more epic. As the tracks get bigger, the more complicated the distribution becomes, as it turns out, hosting 3.9 TB audio files isn't as easy as it sounds. Nor is playing them, as iTunes, Winamp and Windows Media Player don't care much for daylong songs. For now, you'll be able to stream most of it at their website, although the chances of you actually listening to it all is pretty slim.
If you'd prefer to see the action live, there are rumors of a live performance happening soon at Denver Noise Fest, which should be releasing its lineup tomorrow.
